,SPECIFICATION forming part of Letters Patent No. 746,729, datedDecember 15, 1903.

Application tiled July 27, 1903. Serial No. 167,152. (No model.) A

vin the county of Licking and State of Ohio,

have invented certain new and useful Improvements in Car-Couplings; andIdo hereby declare the following to be a full, clear,and exy actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of this invention is to provide an improved coupling ofsimpliiied construction of the kind adapted to automatically couple thecars.

The invention consists in the construction hereinafter described andclaimed.

In the accompanying drawings, showing an embodiment of the invention,Figure 1 is a horizontal sectional view of the draw-head, exposing intop plan view the operative parts of one coupler in the coupledposition. Fig. 2 is a similar view showing the same parts in uncoupledposition. Fig. 3 is a similar view showing the same parts in coupledposition on a curved track. Fig. 4 is a vertical sectional view showingin full lines the lock down and in broken lines the lock up. Fig. 5 is afront or end view showingthe coupled position oi' the parts. Fig. 6 is aperspective of the lock. Fig. 7 is a perspective view of a lever orkicker for moving the knuckle to open position. Fig. 8is a perspectiveof the knuckle.

Like characters of reference designate corresponding parts.

The draw-head 1 has an appropriate cavity to receive the inner leg oftheknuckle 2, the lock 3, and the kicker 4. The draw-head also has aboxed-in cavity or hood la above the main cavity, into which the lockcan he lifted and guided. The knuckle 2 has a leg 2?, on the outer sideof the end of which are formed lock-engaging shoulders 2b and 2, theshoulder 2c being set back of the shoulder 2" and having adjacentthereto a seat 2d, upon which the lock rests when engaging the saidshoulder 2. rear side a toe 2e, adapted to engage a projection 1b in thehead of the cavity, as hereinafter described.

The lockl 3 consists of a rectangularly- K shaped block having averticalrib 3a project- The knuckle-leg 2a also has at its ing from its side andat its lower end a stud 3b projecting horizontally from the rib. Thelock slides vertically in an opening in the upper wall of the draw-head,the edges 3 and 3d serving to guide and hold the lock from horizontalplay. Attached to the upper end of the lock is a rod 3e, passing upthrough the hood la, by means of which the lock can he lifted.

The kicker or knuckle-opening device 4 consists of a bell-crank lever.ThisV is fulcrumed on a pin 4? in the upper wall of the draw-head inrear of the knuckle and in such position that the lower end of thedepending arm 4b' of the lever may strike the legv of the knuckle and.impel it outward to open position. The end of the arm 4J can be maderounded, so asr to properly bear upon the leg. The upper arm 4. of thekicker reaches forward, soas to lie above and in the path of the stud 3bon the lock 3.

The operation is as follows: Assuming the parts to be iu the positionindicated in Fig.

l and it is desired to put the parts into position to couple, the lockis lifted until the stud 3b strikes and lifts the upper arm of thekicker. ward, as seen in Fig. 2. In this position the lock will rest onthe upper face oi' the end of 'the leg, and iu this position thecoupling will be ready to connect with another.. When hit with anotherapproaching coupling, the lock will drop by gravity, rst on the seat 2dand then to the floor of the draw-head cavity. lf the cars come togetherona curved track, the lock will stop on the seat 2d and the knuckle willbe locked and the cars coupled by the engagement of the. rib 3a andprojection 3b with the shoulder 2C. When the cars run onto a straighttrack, the knuckles are automatically, by the alinement of the cars,turned into position where the lock will drop, so that the rib 8a andprojection 3b will engage the shoulder 2b. When the cars come together,in the first instance,'on a straight track, the lock Will not stop onthe seat 2d, but pass immediately down to the last-described position.tion shown does not operate the kicker until it is lifted high enough topermit the leg of the knuckle to pass under the lower end of The lock inthe construc- This will` throw the knuckle outthe lock. The lower end ofthe lock when completely down is braced by a projection 1c on the bottomof the coupler-cavity.

What I claim, and desire to secure by Letters Patent, isv l. In acar-coupling, the combination of the knuckle having a leg with alock-engaging shoulder, a lever having one arm adapted to actuate theleg to throw the knuckle into uncoupled position, a sliding lock havinga rib 3LA with a projection 3b at its lower end, said rib and projection3b to engage the leg of the knuckle, and the projection 3b also toactuate the other arm of the aforesaid lever.
